A point lies on the -axis, 7 units to the left of the origin. Its reflection across the -axis is then taken.
What are the coordinates of the reflected point?

Class 8Plotting PointsCoordinate Geometry
  • A(7, 0)
  • B(-7, 0)
  • C(0, 7)
  • D(0, -7)

Step-by-Step Solution

The original point is (-7, 0). Reflecting across the -axis changes the sign of : (-7, 0) becomes (7, 0).
Answer: A) (7, 0)
